Could you build this?
No This represents cutting-edge machine learning research in non-Euclidean representation learning and hyperbolic/curved sparse autoencoders for mechanistic interpretability.
What it would actually take: Requires implementing non-Euclidean manifold geometry (such as Poincaré ball or Lorentz models of hyperbolic space) into neural network layers and sparse autoencoder loss formulations in PyTorch/JAX. It involves deriving Riemannian optimization gradients (e.g., Riemannian Adam) and running massive GPU training runs to train 16k+ feature autoencoders on LLM residual streams. Deep expertise in geometric deep learning and mechanistic interpretability is mandatory.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
